Prescriptions

Sphere (SPH) stands for the prescription power in diopters. Sphere indicates how much magnifying power your lenses must provide to correct your vision.

Cylinder (CYL) is the amount of lens power needed to correct your astigmatism. Astigmatism is a condition where your cornea is irregularly shaped causing blurred vision. If no cylinder power is stated in your eyeglass prescription, you have no astigmatism and you should leave these boxes blank when ordering.

AXIS indicates the degree and direction of your astigmatism. If no cylinder power is stated in your eyeglass prescription, you have no astigmatism and you should leave these boxes blank when ordering.

Pupillary distance (PD) is the distance between the centers of the pupils in your eyes, shown in millimeters. Pupillary distance is used to align lenses over the center of your pupils for perfect clarity.

The lenses are provided by internationally acclaimed company with over 40-year-long tradition. They feature 100% UV-protection, anti-reflective, scratch-resistant and water-repellent coating.
